A grand touring sports coupe (2+2) with a gas powertrain. Below: the service intervals with real cost ranges, the repairs GranTurismo owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Known repair windows
What GranTurismo owners actually run into

Operator notes
New (2023+) generation, Nettuno 3.0L twin-turbo V6 with pre-chamber combustion and dual (port + direct) injection that limits GDI carbon buildup. Timing CHAIN. Annual or ~12,500 mi service; spark plugs ~3 yr, belts/air filters ~4 yr. A GranTurismo Folgore trim is a tri-motor 800V EV (no oil, separate BEV schedule). Requires premium full-synthetic oil.
When the smart money sells
On fleet math, a gas GranTurismo retires around 95,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
